I've managed to generate a 9.8.2 bootstrap kit, using the same approach 
as for Rust.  I needed to let hadrian build the wrong bootstrap first, 
and then unpacked it and fixed it up.  It's in the usual place.

I needed an extra patch to turn off split sections, as the linker script 
is specific to GNU ld.  ChatGPT helped me write this patch as I know 
zero haskell:

There's probably a cleaner way, I'll leave it to you to re-work and 
integrate as necessary.

Cheers,
